DUMPlNG-BUCKET.

SPECIFICATION forming part of Letters Patent 1 0. 784.815, dated March 14;, 1905.

Application filed February 10, 1904. Serial 1 To It 11/71/0112, it may concern.-

Be it known that LGUs'rAvUs L. SrUnnNnR, a citizen of the United States, and a resident of Flushing, in the county of Queens and State of New York, have invented certain new and useful Improvements in Dumping-Buckets, of which the following is a specification.

This invention relates to dumping-buckets; and one of its specific objects is the production of a bottom-dumping bucket with an automatic closing device.

Referring to the drawings, Figure l represents an outside view of my improved bucket. Fig. 2 shows a vertical section of Fig. 1 on the line in Fig. 8 is a partial section of Fig. 2 on the line :0 m. Fig. L is a partial reproduction of Fig. 2 with the movable elements in a different position. Fig. 5 shows a bottom View of the swinging bottom of the bucket.

The organization of the invention comprises the sides or body of a bucket, with a swinging bottom hinged thereto, the said bottom counterbalanced by a weight to automatically close the bucket, and means to release the action of the counterweight to allow the bottom to swing from the bucket by the weight or pressure of the charge contained therein.

The bucket is shown with its body portion A, in which there is formed a pocket B B for the manipulation of the counterweight C, with its appurtenances, and one of the ends of the swinging bottom D, which is under the said pocket. The pocket also forms a guide for j the said counterweight. The counterweight U is recessed at C to make clearance for the handle 6 of a latch E, and the latter carries a roller E, that in the closed position of the swinging bottom bears on the top face (J of the said counterweight. At the end of the handle 0 there is generally formed an eye or ring 0 The roller E is j ournaled in the bearings c formed in the upper end of the said latch E, which latter is pivoted,by means of the pin F, to the plates G, that extend through an opening H, formed in the body of the bucket. The said opening H is narrowed at its lower portion H to maintain the lower end of the handle 6 of latch outside of the body of the bucket by means of the lugs e, that project from the said handle and extend beyond the edges of the lower portion H of the said opening when the roller E is bearing down upon the counterweight C.

The bucket is provided with a bail L, swinging on pivots 1, extending from the bucket in the usual manner.

The pocket B B is formed by means of the plates 6 b, which latter are joined together and with the body of the bucket. Braces b extend from the lower side of the plate 5 and at the lower ends are formed into eyes'b.

The swinging bottom D consists of the angles (Z and (Z which carry the filling-pieces dflthat are covered by the plate (Z An angle iron M connects the angles of the swinging bottom to strengthen the latter, and form a guide for the counterweight. Plates H extend from the angles (Z and in which are formed bearings for a pin 1, that carries a roller 1 Extending through the swinging bottom D are the staples J, held in place by the nuts J and which, with the eyes a and a rod K,constitutea hinge for the said swinging bottom, which hinge, it will be noted, is located in the pocket B B.

On the inside of the upper portion B of the pocket B B there are secured angle-irons Z! U, the latter of which are fastened to the body of the bucket, and all the said angle-irons supn port the plate I) of the pocket, and at the lower end a ring 6 joins the angle-irons 7)" b with the body of the bucket.

To operate the invention, and when the bucket is to be filled with its load or charge, the moving parts are disposed as shown particularly in Fig. 1, the bottom D closing the bucket, the lower face of the counterweight bearing against theroller I of the swinging bottom D, and the roller E of the latch E bearing down on the said counterweight, keeping the same in proper position. \V hen it is desired to dump the charge from the bucket, the handle a is raised, as shown in Fig. 4, when the roller IE will be swung clear of the upper face of the counterweight, and the charge bearing down on the inner face of the swinging bottom will cause it to swing down and allow the contents of the bucket to be discharged, the roller 1 bearing up against the bottom face of the counterweight,and after the charge 1 and thereby'automatically close the bottom has been emptied from the bucket the counterweight will automatically descend and bear on the roller I while at the same time the latch will automatically find its place on the top face 0 of the counterweight and automatically lock the moving elements in position for again filling or charging the bucket.

Having described my invention, I claim 1. In a bucket the combination of a swinging bottom connected thereto, a pocket in the bucket, a counterweight guided in the pocket and located to bear on the swinging bottom, and thereby close the said bottom against the body of the bucket.

2. In a bucket the combination of a hinge, a bottom swinging from the hinge and extending on opposite sides thereof, a pocket in the bucket, a counterweight guided in said pocket with its lower face arranged to bear against one of the ends of said swinging bottom, a latch hinged to the bucket and arranged to bear against the top face of said counterweight.

3. In a bucket the combination of a hinge thereon, a bottom of the bucket swinging on the hinge, a latch pivoted to the body of the bucket, a pocket in the bucket, a counterweight guided in the pocket and arranged to bear between one end of said bottom and the said latch, means to disengage the latch from the counterweight.

4. In a bucket the combination of a door swinging therefrom, a pocket in the bucket, a counterweight guided in said pocket and arranged to bear on one end of the door to maintain it closed, and means to allow a charge in the bucket to bear against the door and raise the counterweight.

5. In a bucket the combination of a swinging bottom hinged thereto, a pocket formed in the bucket, a counterweight arranged to move in the said pocket, a latch pivoted on the bucket and arranged to swing into and out of the said pocket, one end of the latch capable of bearing on one end of the counterweight, and one end of the swinging bottom capable of bearing on the opposite end of the counterweight.

6. In a bucket the combination of a swinging bottom thereon, a pocket in the bucket, a counterweight guided in the pocket and arranged to bear against one end of the bottom,

against the bucket, a latch pivoted on the bucket and arranged to bear against the said counterweight to keep the bottom against the bucket, means to detach the latch from the counterweight to allow the latter to move, by virtue of the end of the swinging bottom bearing thereon, when the latter is swinging from the body of the bucket.

7. In a bucket the combination of a pocket formed therein, a latch pivoted in the sides of the bucket and swinging into and out of the pocket through an opening in the body of the bucket, a roller in the end of the latch entering the pocket, and a handle at the end of the latch, lugs on the handle to prevent the latter entering the said pocket, a hinge formed in the lower end of the pocket, a swinging bottom connected to the bucket with the said hinge, a roller journaled at the end of the swinging bottom, and a counterweight arranged in the pocket to bear between the latter roller and the roller in the latch.

8. In a bucket the combination of a pocket formed thereon, angle-plates extending from the body of the bucket and inserted in an opening in the body of the bucket leading to the said pocket, a latch pivoted in the said plates, a roller journaled in one end of the latch, and a handle at the other end of the latch, a counterweight in the pocket having a recess to clear the said angle-plates and to be-stopped by the latter when moving up, a swinging bottom hinged to the bucket, a roller at one end of said bottom bearing up against the said weight, the roller on the latch bearing down on the counterweight when in a locked position, and free from the counterweight when unlocked, and a bail pivoted from the bucket.

9. In a bucket the combination of a pocket formed therein, a counterweight guided in the said pocket, a swinging bottom with one end located to swing into and out of the pocket and bear against the counterweight, and a hinge for the swinging bottom located in the pocket.
